The Institute of Information and Communication Technologies Bulgarian Academy of Sciences (IICT-BAS) is founded on 1st of July 2010 as a successor of the Institute for Parallel Processing, Institute of Information Technologies and Institute of Computer and Communication Systems. The institute integrates the strongest Bulgarian groups in: large-scale high-performance computations, parallel algorithms, Grid and Cloud, linguistic and semantic technologies, intelligent systems, signal and image processing. The institute is a core partner for SEE region in different HPC-related project. IICT-BAS coordinated the 5-year national SuperCA++ project, establishing a Centre of Excellence for developing of supercomputer applications, which includes several universities and institutes. The institute supported the development of HPC applications from different areas of science, e.g. environmental protection, semiconductor physics, biomedicine and bioinformatics and targeting different architectures-clusters, GPU and supercomputers. In the last few year, IICT-BAS established cooperation with SMEs working in different arias of Bulgarian economics. As an owner of the Advanced Computing and Data Centre ( IICT-BAS provides HPC resources to the industry and academia.
